做个红色线(CR线)上拐选股公式

请老师帮忙做个红色线(CR线)上拐选股公式. 谢谢! N:=25;M1:=5; MID := (HIGH+LOW+CLOSE)/3; CR:SUM(MAX(0,HIGH-REF(MID,1)),N)/SUM(MAX(0,REF(MID,1)-L),N)*100,colorred,linethick2; MA1:REF(MA(CR,M1),M1/2.5+1),colorwhite,linethick2; 过热:250; 追击:140,colorred; 试探:120,colorgreen; 吸筹:50;

爱约股解答：

N:=25;

MID:=(HIGH+LOW+CLOSE)/3;    

CR:SUM(MAX(0,HIGH-REF(MID,1)),N)/SUM(MAX(0,REF(MID,1)-L),N)*100;  

REF(CR,1)<REF(CR,2) AND CR>REF(CR,1);
